Could it be "Jack-in-the-pulpit," Arisaema triphyllum? If so, it is a native plant that likes moist shade and makes a bloom a little similar to a calla lily, but striped kind of green and beige or maroon and green. It usually grows in small colonies.

If you were expecting that you are growing a tropical, I could take another stab at it.

If I planted it... I sure don't remember!
When I took the plants out after winter, the Orchid that was in that pot had died and this had sprung up.
Again... probably too early to try to ID. But I'm sure keeping an eye on it!
Thanks!
